SPECIFICATION formingpart of Letters Patent No. 729,154, dated May 26,1903.

Application filed April 9, 1902. Serial No. 102,140. (No model.)

To all whmn it may concern:

Be it known that I, FRANK LESLIE GAUS- DEN, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Patch for Mending Saws, ofwhich the following is a specification.

My invention has reference to the repairing of cracked or fracturedsaw-plates; and it consists of a double patch, as will be fully setforth hereinafter in connection with the accompanying drawings. I attainthese objects in the following manner, illustrated in the accompanyingdrawings, in which Figure 1 is an elevation of a portion of a plate,showing my improved patch applied. Fig. 2 is a detail perspective viewof a portion of plate, showing plate prepared for a patch. Fig. 3 is anenlarged sectional view on line 3 3, Fig. 1, showing plate prepared forpatch. Fig. 4 is a similar view showing the patch in place. Fig. 5 is asimilar view showing the patch after it has been brazed and finishedflush with the plate. Fig. 6 is an enlarged sectional view on line 6 6,Fig. l, b to be dressed ofi. Fig. 7 is a similar section showing amodified form of construction.

Similar letters refer to similar parts throughout the several views.

The plateAin Fig. 1 shows patch B applied and brazed by solder O. Thisis a finished patch, opposite side of plate showing the same.

The plate A, Fig. 2, shows plate grounder filed, as at a ready toreceive patch. a represents crack in plate. Opposite side of plate Afinished in same manner.

B is the patch ready to place on plate A.

b is the convex or inside of patch.

I) shows ends of patch finished in like manner. Solder is bent same aspatch and placed between plate A and patch B. IIot irons are thenapplied.

Two single patches may be used, as in Fig. 7, B, and a piece of steel ormetal made, as D, to hold them in place. The double patch is made so asto slip on over the crack on band-saws or steel plates when they arefitted to receive them. The patches may be made separate and thin pieceof sheet-steel made to slip over them and hold them in place whenbrazing.

The part which is new or my improvement is one patch opposite anotherpatch and the manner of making a double clamp-patch.

I claim A patch for mending saws consisting of a U-shaped piece of metalhaving its legs in juxtaposition throughout their length, each leg beingsegmental in cross section, the curved faces being opposed to eachother, substantially as shown and described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FRANK LESLIE GAUSDEN.
